A 0.3288-g sample of a hydrocarbon was burned in air. The sample was entirely converted to 1.0562-g of carbon dioxide and 0.5046-g of water. Determine the empirical formula of this compound
Consider the reaction shown below. PbCO3(s) PbO(s) + CO2(g) Calculate the equilibrium pressure of CO2 in the system at the following temperatures.
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13).
